Tracking a steep rise in local stocks, the rupee today sharply appreciated by 61 paise, its biggest gain in two months, to end at 54.84 helped by capital inflows worth nearly USD 300 million and sustained dollar sales by exporters.

Weak dollar overseas and rising hopes of government being able to push through reforms helped rupee rise, said dealers.

At the Interbank Foreign Exchange (Forex) market, the domestic unit opened lower at 55.55 a dollar from Tuesday's close of 55.45 and immediately touched a low of 55.61 on early hesitance in stocks.

However, later it bounced back to a high of 54.76 before settling at nearly two-week high of 54.84 -- a rise of 61 paise or 1.10 per cent. Previously, it had finished at 54.70 on November 15, 2012.

The 61 paise gain today is the highest single-day gain after the currency registered a rise of 93 paise or 1.71 per cent against the US dollar on September 21, 2012.

The logjam in Parliament over FDI in retail ended today with a discussion on the issue allowed with voting.

FIIs pumped in around USD 300 million (or Rs 1,580 crore) in Indian stocks, as per provisional data with bourses.

The dollar index was down by 0.22 per cent against a basket of six major currencies as investors yesterday heard optimism from Washington about budget talks that could allow

the US economy to avert tax hikes and spending cuts.

"The very important India GDP figures for July-September 2012 period will come out tomorrow. Weaker data would hamper the positive sentiments build on the hopes of new reforms," said Abhishek Goenka, Founder & CEO, India Forex Advisors.

Meanwhile, the Indian benchmark sensex today zoomed by 328.83 points or 1.75 per cent to end at a 19-month high of 19,170.91 after Goldman Sachs upgraded its recommendation on India to overweight from market-weight.

Pramit Brahmbhatt, CEO, Alpari Financial Services (India) said: "The rupee appreciated sharply tracking easing of political logjam and positive global market cues supported by the rising optimism that the US senate and Whitehouse will come up with budget deal avoiding the fiscal cliff.

"The Euro and GBP strengthened against dollar on risk on sentiments in global markets."
